HAT-FORIVIING MACHINE.

SPECFICATON forming part of Letters Patent- No.323,023, dated July 28,1885.

Application filed February 17, 1885.

To all whom it may concern:

- Be it known that I, ISAAC F. BROWN, of Hyde Park, in the county ofNorfolk and State of Massachusetts,a citizen of the United States, haveinvented a new and useful Improvement in Hat-Forming Machines, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part of this specificationin explaining its nature.

Heretofore it has been customary, in operating hat-forming machines, tofirst weigh the wool which forms the bat, and then to feed it to thecarding-machine, which forms it into a bat and delivers it to thehat-forming cone; and as lthe wool used is weighed before it is put intothe cardingmachine, and as it is necessary to deliver cach quantity thusweighed to the receiving-cone, and as the operator who is attending thedelivery of the bat upon the cone cannot know that the bat is ready fordelivery until informed by the operator who weighs the bat and feeds itto the carding-machine, itfollows that there is a considerable loss oftimein the operation which might be saved if the operation of thecarding-machine were to some extent continuous, if there were nonecessity for first weighing the wool, and if notice were given when aproper supply or quantity of the bat had been fed to the cone; and myinvention relates especially to a device whereby this improvement in theoperation of the machine is produced, namely, whereby the wool may bcfed to the carding-machine without being weighed, and when a sufficientquantity has been fed to the cone shall indicate that such quant-ity hasbeen fed, so that the operator of the cone may k now that a suflicientquantity has been fed to the cone and may cut the bat.

The improvement consists, especially, of a device adapted to be operatedby the doftershaft or some other revolving part of the cardingmachine,and to indicate when a predetermined quantity or amount of bat has beenformed and fed, and as the bat is formed regularly and uniformly, sothat a certain area of it will weigh so much, the necessity of previousweighing, if the extent and area which has been fed is known, becomesunnecessary, and the wool can be fed continuously, so that substantiallya continuous bat can be formed.

l j Referringto the drawings, Figure 1 is a front elevation of a machinecontaining the features of my invention. Fig. 2 is a plan view thereof.Fig. 8 is an elevation, enlarged. Fig. 4 is a vertical section upon theline yy of Fig. l. Fig, 5 is a representation of the back side of themachine with the gong removed. Fig. 6 is a detail view. Fig. 7 is avertical section upon the line sv x of Fig. l.

A represents the shaft of a doffer, and upon its end is mounted thespur-gear a, which meshes witha spur-gear, a', upon the shaft a2. Thisshaft is supported by the bracket c3, which is bolted or otherwisesecured to the frame of the machine, and carries at its front end thebevel-gear at, which meshes with the bevel-gear a5 upon the shaft as.This shaft is supported at its inner end by the sleeve a7 upon the arma8, which has bearings a9 upon the shaft c2, so that the shaft c has avertical swinging movement upon the shaft a2. This movement is providedthe shaft for reasons which will hereinafter appear. The shaft a carriesa cam, B, and a worm, C, which engages with the spurgear c and revolvesthe same. It preferably has at its outer end the weight c for holdingthe worm down to its work, and for insuring the quicky return of theshaft when operated, as hereinafter described. It is desirable that thedevice should beso constructed that once adjusted it shall alwaysindicate,un til otherwise adjusted,the delivery of apredeterminedquantity or length of bat. It is also necessary to provide the devicewith an adjustment whereby it may be set to indicate the delivery of batof any length for hats of all sizes and weights. These objects areaccomplished by mechanism which governs the time of contact of the wormwith the spurgear, and it comprises the wheel or disk D, upon the shankd which has a dovetail or 11ndercut recess, d,on its face which receivesthe end d2, of a bolt, d3, which passes through the end of the arm orlever (hand which is clamped to the wheel by means of the clamping-screwd5, so that,upon the revolution of the plate or wheel D, the lever,which is secured to the shaft d is caused to be moved to operate thedevice for disengaging the worm C from the gear o. The wheel carryingthe lever is moved upon contact of the pin or projection c2 on thespur-wheel c with the pin or projection d,

ICO

which extends through the upper end of the arm or lever (1*, and thismovement of the lever causes the pin dwhioh enters the slot e in ahorizontal arm, E, to finally come in contact with the arm and move ithorizontally in the direction of the movement of the spur wheel andlever d4, and this movement of the arm operates to lift the latch e, onthe end of the bell-crank lever which is pivoted at c3, from the studorvpin e'1 Aupon the swinging block e5, and this swinging block,upontherelease of the latch and the movement of the shaft a, so as to bringthe cam B into proper position ,is drawn under the cam by the spring e,so that the cam will rest thereon, and upon the continued revolution ofthe shaft it is apparent that the cam will ride upon the uppeiI surfaceof this block or piece and will lift the shaft a. so as to disengage theworm from the gear c, and when the worm is so disengageda spring, F, oneend of which is attached to theY bracket and the other to thespur-wheel, serves to return the spur-wheel to its original position,and at the same ti meto reverse the movement of the lever d* and thedisk or wheel D, and this reverse movement ofthe lever causes the pinZ,Whiclr enters the slot g in the horizontal bar G attached to t-heswinging block eto be moved backward sufciently to bring the latch studor pin e in line with the recess in the latch e,which shutsautomatically there` on and holds it in that position until it is againreleased upon the forward movement of the lever d4. The disk or wheel Dhas a projection, H, against which the stud or pin c2 on the spur-wheelc strikes upon its backward movement; and it serves two purposes, first,as the wheel D has been moved a portion of a revolution upon the forwardrevolution of the lever d it upon the reverse movement ofthe spur-wheelc, and upon contact with the lu g 0r projection c2 therewith, moves thelever or arm d4 back to its original position;l second, it then acts asa stop in preventing the further reverse movement of the spurwheel. Itis obvious that by changing the position of this stop H that the extentof the movement ot' the spur-wheel,befo1e the disengagement of theworin, may be varied-that is, by moving the stop in one direction thespur-wheel will make a larger part of a revolution before thedisengagementof the worm, and that moving it in the opposite directionit will make a smaller portion of a revolution; and this movement of thestop is accomplished by simply loosening'thclocking-nut Z5 at thelowerend of the arm or lever d", and turning the disk or wheel D to bring thestop H into the desired position, when the locking-nut is again turnedto clamp and lock thelever to the wheel.

To indicate when the spur-gear has reached the end of the movement whichit is set to make, I have arranged upon the shaft d the lever M, whichcarries at its end the pawl m, which has the inclined surface m, onwhich the end m2 of the bell-crank lever ma rides as the lever M isbeing moved forward, so that the forward movement causes the tongue orstriker m4 to be brought in contactlwith the gong or bell. Immediatelyfollowing the striking of the bell ,the end m2 ofthe lever rides overthe pawl, and upon the backward or reverse movement of the lever M thepawl moves on its pivot backward until it has cleared the end of thebell-crank lever, when,by the spring ma, it is returned to its originalposition, or that represented in Fig. 4. The spring m serves to keep theend m2 of the lever mi in contact with the pawl.

I of course do not confine myself to the especial form of mechanism forconnecting the shaft d with the bell-halnmer, but may use any mechanicalequivalent for the device herein described.

The disk D may be provided with marks to indicatewhere it should be setto indicate the feed of varying lengths or quantities of bat. Inpractice the disk or wheel D is set to cause the alarm to be soundedupon the doifer running the number of revolutions which it is necessaryfor it to make in producing the quantity or weight of bat which the hatthen being made requires, and upon the revolution of the doffer movementis communicated to the spur-wheel c, which is revolved until it causesthe operation of the tripping mechanism, which allows to be brought intoplace the device upon which the cam rides in automatically disengagingthe driving mechanism, and upon the disengagement the parts ret-urnautomatically to their normal position, the worm again engages with theteeth of the spur-wheel, and upon the operation of the doffer the deviceis again operated as before, and theala'rm sounded to indicate the timewhen a certain extent or quantity of the bat has been made and fed.

It will be observed that the lever or arm (Z4, attached to the wheel ordisk D, operates to trip the latch c, which permits the caml'ifter to bemoved into operative position. It will also be vseen thatV upon `thereverse movement of the spur-wheel the cam-lifter is withdrawn, held,and latched back by the latch e.

Of course, while I have illustrated this indicating device as especiallyadapted for operation upon a hat-iorming machine, yet I would not beunderstood as limiting the invention to that class of machines, forofcourse it may be used upon any machine where it is desired that analarm shall be sounded or indicated at the end of a certain number ofrevolutions of any part of the machine.

I have referred to the machine to which my invention is applied as ahat-forming machine. I mean to be understood by that, a machine whichconsists of the wool-carding machine, which prepares and feeds the bat,and the machine which receives the bat from the wool-carding machine andwinds it about the hat-forming cone.

Of course the invention can be applied to any wool-carding machine whereit is desired IOO IIO

IIS

to indicate the quantity, Weight, or Width of the bat being carded andfed. j

Having thus fully described my invention,
